Kompaktors | Roller Presses

A roller press, also known as a kompaktor, roller press or briquetting press, is used to compact fine-grained materials into solid press agglomerates. This can be used to produce flakes or briquettes. In combination with grinding and classification technologies, it is possible to achieve dry granulation.

In kompaktors, the powdery bulk material is compacted between two counter-rotating rollers. As the material is drawn into the roller gap, it is subjected to compressive forces, resulting in the formation of effective binding forces between the particles.

Advantages of compacting for your product and production

Improvement of the flow properties
Reduction of dust pollution,
Improvement of the through-flow
Improvement of the distribution behaviour
Customised particle size and shape
Increased bulk density
Modified reaction behaviour (such as solubility)

Dry granulation and wet granulation

There are two different processes for granulation:

Dry granulation:

Compacting and subsequent grinding
No addition of binders required
No drying necessary
Especially for products that are sensitive to heat or moisture
End product: granular, free-flowing mixture of uniform size

Wet granulation:

Addition of binders in liquid form (water or alcohol-based)
Drying process necessary
Granulation following compaction and drying
Possible negative impact on the quality of the granules

Hosokawa Alpine compaction (formerly Hosokawa Bepex)

In 2013, the compacting business unit of Hosokawa Bepex was integrated into our powder and particle processing business unit and has since been called Hoskoawa Alpine Compaction. The former Hosokawa Bepex confectionery business was taken over by the Bühler Group in 2015.

Of course, we still offer service for your Hosokawa Bepex machines. Our experts will be happy to help you with your request.
